Britney Spears' ex-husband Kevin Federline, known for making his own name as a rapper and a dancer, has been hospitalized in Australia after suffering from chest pains and a quick pulse. After being tested clear of a minor heart attack, K-Fed's condition could have easily been angina what with its similarities, so with that said, how would people know if it is angina?

Federline suffered through what was suspected to be a minor heart attack after doing drills with the Greater Western Sydney AFL team, where he complained feeling chest pains and a "racing pulse," reported the Herald Sun. With some of Federline's lifestyle choices, such as smoking and drinking, what he went through could have been an angina - commonly known as a minor or a mild heart attack.

If people are wondering where it got its name from, angina pectoris is actually Latin for squeezing of the chest, according to MedicineNet.com. The frightful episode of chest discomfort occurs when there is a decreased supply of oxygen or blood in the area of the heart muscle, usually because of a blockage or the narrowing of the arteries.

Just like in K-Fed's case, angina is triggered during physical exertion, while other triggers are severe emotional stress or consuming a heavy meal. However, the difference between what the rapper felt and angina is that when suffering from an angina, its symptoms are any unpleasant feeling across the chest, which can extend to the neck, jaw, arms, back, and even the teeth.

People who are suffering from angina could also feel: indigestion, heartburn, weakness, sweating, nausea, cramping, shortness of breath, sensation of choking in the throat, and heaviness in the upper abdomen, according to Heart-Attack-Symptoms.com.

When the symptoms do come up, do not panic. Instead, what people should do is to stop whatever they are doing, have a seat and prop both feet up until the pain subsides. But when angina does happen when a person is lying down or sleeping, what they should do is to sit up or stand up, so that the heart experiences less pressure, according to StreetDirectory.com.

But aside from trying to manage the pains of angina, there are some things that people can do to prevent angina all together. For starters, don't take breathing deeply for granted. Angina usually occurs when someone is stressed, and to prevent this, calm down, take it slow, and take deep breaths.

And as for smokers, it's probably best to start trying to kick the habit away as smoking robs the blood of oxygen, and at the same time, nicotine constricts the blood vessels, which helps trigger angina since the mild heart attack occurs due to constricted arteries.

Some other tricks of the trade in preventing an angina from occurring is to take an adult aspirin tablet daily, that's about 325 milligrams, as studies have shown that just by taking it decreases the likelihood of heart attacks. Another tip, which is quite surprising, is to take it slow when waking up in the morning as the heart is quite sensitive in the early hours.
